Calls going from one IVR to another

[3CTEL]

We have 2 different IVRs, each IVR has it's own DID.
Issue is sometimes calls from one IVR are going directly to the users. IVRs should be directing calls to queues only but at times calls are going to users as well as queues that are not on that IVR. For example queues that can be selected from this specific IVR are 1003,1004 but the calls are going to 1008 as well. This is happening randomly.
Can you advice what is happening?

The IVRs allow callers to dial extension numbers. It is possible that someone is just dialling extensions at random.

I am attaching a call log screenshot here, in the log call went to IVR 80013 and from there to queue 80023 which is ok. But from there it went to IVR 80002 -> queue 80009 -> user 29024 which should not be happening because it is a different IVR.
